The output pulse width is variable from 10 to 200 ns. The rise and fall times are fixed at less than 150 ps. Instruments with the "-P" model suffix can generate 0 to +10V, whereas instruments with the "-N" model suffix can generate 0 to -10V. Instruments with the "-PN" suffix can generate both polarities. The AVMR-1A-B is a highly flexible instrument. Aside from the internal trigger source, it can also be triggered or gated by external TTL-level signals. A front-p anel pushbutton or a computer command can also be used to trigger the instrument. The AVMR-1A-B features front panel keyboard and adjust knob control of the output pulse parameters along with a four line by 40-character backlit LCD dis play of the output amplitude, pulse width, pulse repetition frequency, and delay. T he instrument includes memory to store up to four complete instrument setups. The ope rator may use the front panel or the computer interface to store a complete “snapshot ” of all key instrument settings, and recall this setup at a later time. This instrument is intended for use in research and development laborat ories. AVAILABLE OPTIONS The AVMR-1A-B is available with several options: -OT Option: this option adds an internally-generated 0 to ±5V DC offset to the main output. -EO Option: the DC offset can be controlled by an externally generated 0 to +10V analog control voltage. -EA Option: the amplitude can be controlled by an externally generated 0 to +10V analog control voltage. -M Option: a monitor output is provided. -R5 Option: A rack mounting kit is available. The -R5 rack mount kit ma y be installed after first removing the one Phillips screw on the side panel adjacent to the front handle. -TNT Option: Adds a rear-panel Ethernet connector, providing Telnet-bas ed remote control from a network. __________________________________________________________________ 6 SPECIFICATIONS Model: AVMR-1A-B1 Amplitude2,3: (50 Ohm load) Variable to 10 Volts Pulse width: 10 to 200 ns PRF: 0 to 10 MHz Maximum duty cycle: 10%.

P OWER Switch . This is the main power switch. When turning the instrum ent on, there may be a delay of several seconds before the instrument appears t o respond. 2. O VERLOAD Indicator . When the instrument is powered, this indicator is normally green, indicating normal operation. If this indicator is yellow, an int ernal automatic overload protection circuit has been tripped. If the unit is overloaded (by operating at an exceedingly high duty cycle or by operating into a very low imped ance), the protective circuit will disable the output of the instrument and turn t he indicator light yellow. The light will stay yellow (i.e. output disabled) for about 5 s econds after which the instrument will attempt to re-enable the output (i.e. light g reen) for about 1 second. If the overload condition persists, the output will be disabl ed again (i.e. light yellow) for another 5 seconds. If the overload condition has been removed, the instrument will resume normal operation. This overload indicator may flash yellow briefly at start-up. This is n ot a cause for concern. Note that the output stage will safely withstand a short-circuited load condition. 3. O UT CONNECTOR . This connector provides the main output signal, into l oad impedances of 50 Ohms. A 50 Ohm load is required. 4. S YNC OUT . This connector supplies a SYNC output that can be used to t rigger other equipment, particularly oscilloscopes. This signal leads (or lags ) the main output by a duration set by the "DELAY" controls and has an approximate amplitude of +3 Volts to RL > 1 kΩ with a pulse width of approximately 100 ns. 5. L IQUID CRYSTAL DISPLAY (LCD) . This LCD is used in conjunction with th e keypad to change the instrument settings. Normally, the main menu is di splayed, which lists the key adjustable parameters and their current values. The “Programming Manual for -B Instruments” describes the menus and submenu s in __________________________________________________________________ 15 detail. 6. K EYPAD . Control Name Function MOVE This moves the arrow pointer on the display. CHANGE This is used to enter the submenu, or to select the operating mode, pointed to by the arrow pointer. ×10 If one of the adjustable numeric parameters is displayed, this increases the setting by a factor of ten. ÷10 If one of the adjustable numeric parameters is displayed, this decreases the setting by a factor of ten. +/- If one of the adjustable numeric parameters is displayed, and this parameter can be both positive or negative, this changes the sign of the parameter. EXTRA FINE This changes the step size of the ADJUST knob. In the extra- fine mode, the step size is twenty times finer than in the normal mode. This button switches between the two step sizes. ADJUST This large knob adjusts the value of any displayed numeric adjustable values, such as frequency, pulse width, etc. The adjust step size is set by the "EXTRA FINE" button. When the main menu is displayed, this knob can be used to move the arrow pointer. __________________________________________________________________ 16 REAR PANEL CONTROLS 4 8 11 1 3 5 OS GRN=LNK GATE YEL=ACT MON ON OFF LAN TRIG RS-232 AMP GPIB 9 6 10 12 2 7 1. A C POWER INPUT . An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. O ne end of the detachable power cord that is supplied with the instrument plugs in to this socket. 2. A C FUSE DRAWER . The two fuses that protect the AC input are located i n this drawer. Please see the “FUSES” section of this manual for more informat ion. 3. D C FUSES . These two fuses protect the internal DC power supplies. Ple ase see the “FUSES” sections of this manual for more information. 4. G ATE . This TTL-level (0 and +5V) logic input can be used to gate the triggering of the instrument. This input can be either active high or active low, dep ending on the front panel settings or programming commands. (The instrument triggers normally when this input is unconnected). When set to active high mode, this inp ut is pulled- down to ground by a 1 kΩ resistor. When set to active low mode, this in put is pulled- up to +5V by a 1 kΩ resistor. 5. T RIG . This TTL-level (0 and +5V) logic input can be used to trigger t he instrument, if the instrument is set to triggering externally. The instrument triggers on the rising edge of this input. The input impedance of this input is 1 kΩ. (Dependi ng on the length of cable attached to this input, and the source driving it, it m ay be desirable to add a coaxial 50 Ohm terminator to this input to provide a proper trans mission line termination. The Pasternack (www.pasternack.com) PE6008-50 BNC feed-thr u 50 Ohm terminator is suggested for this purpose.) 6. G PIB Connector . A standard GPIB cable can be attached to this connect or to allow the instrument to be computer-controlled. See the “Programming Manual f or -B __________________________________________________________________ 17 Instruments” for more details on GPIB control. 7. R S-232 Connector. A standard serial cable with a 25-pin male connecto r can be attached to this connector to allow the instrument to be computer-contr olled. See the “Programming Manual for -B Instruments” for more details on RS-232 cont rol. 8. L AN Connector and Indicator . (Optional feature. Present on -TNT units only.) The - TNT option "Internet-enables" Avtech pulse generators by adding this st andard Ethernet port to the rear panel, in addition to the IEEE-488.2 GPIB and RS-232 ports normally found on "-B" units. Commands are sent using the standard Teln et protocol. The SCPI-compliant command set is the same as that used for GPIB and RS -232 control. The -TNT option uses the Dynamic Host Configuration Protocol ( DHCP) to obtain its network address. A DHCP server must be present on the local network for the -TNT option to operate properly. 9. A MP Connector . (Optional feature. Present on -EA units only.) The out put amplitude can be set to track the voltage on this input. Zero Volts in correspond s to zero amplitude output, and +10V in corresponds to maximum amplitude out. Thi s mode is activated by selecting "Ext Control" on the front-panel amplitude menu, or with the "source:voltage external" command. 10. O S Connector . The desired DC offset is applied to this connector. Int ernally, it is connected to the output centre conductor via a high quality RF inductor . Do not exceed ±50V, 250 mA. When the -OT option is present, this connector is only ac tive if the OS switch (item 7) is in the “OFF” position (i.e., the internal offset sou rce is disabled). If this input is not used, it should be connected to ground (zero Volts). 11. O S Switch . This is present for models with the -OT option only. When this switch is set to “ON”, the offset present on the output is controlled by the fron t-panel controls, or by computer commands. When this switch is set to “OFF”, the offset i s controlled by an external voltage applied to the OS connector (item 9). 12. M ON Connector . (Optional feature. Present on "-M" units only.) The mo nitor output provides an attenuated replica (20 dB down) of the voltage on the main output. The monitor output is designed to operate into a 50 Ohm load. __________________________________________________________________ 18 GENERAL INFORMATION BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an ext ernal TTL trigger signal. In either case, two output channels respond to the trigger: OUT and SYNC.  OUT. This is the main output.  SYNC. The SYNC pulse is a fixed-width TTL-level reference pulse used to trigger oscilloscopes or other measurement systems. When the delay is s et to a positive value the SYNC pulse precedes the OUT pulse. When the delay is set to a negative value the SYNC pulse follows the OUT pulse. These pulses are illustrated below, assuming internal triggering and a positive delay: 50 ns, FIXED SYNC OUT (generated by the 3V, FIXED internal oscillator) DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Figure A If the delay is negative, the order of the SYNC and OUT pulses is rever sed: 50 ns, FIXED SYNC OUT (generated by the 3V, FIXED internal oscillator) DELAY < 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Figure B __________________________________________________________________ 19 The next figure illustrates the relationship between the signal when an external TTL- level trigger is used: > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) 50 ns, FIXED SYNC OUT 3V, FIXED DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Figure C As before, if the delay is negative, the order of the SYNC and OUT puls es is reversed. In general, the delay, pulse width, and frequency (when in the internal mode), of the OUT pulse can be varied with front panel controls or via the GPIB or RS -232 computer interfaces. TRIGGER MODES This instrument has four trigger modes:  Internal Trigger: the instrument controls the trigger frequency, and ge nerates the clock internally.  External Trigger: the instrument is triggered by an external TTL-level clock on the back-panel TRIG connector.  Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE” pushbutton.  Hold Trigger: the instrument is set to not trigger at all. These modes can be selected using the front panel trigger menu, or by u sing the appropriate programming commands. (See the “Programming Manual for -B Instruments” for more details.) __________________________________________________________________ 20 GATING MODES Triggering can be suppressed by a TTL-level signal on the rear-panel GA TE connector. The instrument can be set to stop triggering when this input high or lo w, using the front- panel gate menu or the appropriate programming commands. When gated, th e output will complete the full pulse width if the output is high, and then stop triggering. Pulses are not truncated. OPERATION AT LOW AMPLITUDES This instrument will generate the best waveforms when operated near max imum amplitude. If amplitudes less than 1/3 of the full-scale value are desi red, better results will be obtained if the pulse generator is operated at a higher amplitu de, and an attenuator is connected to the output. Avtech recommends the Model ATT- 0527-XX- SMA-07 series of 12 GHz, 20 Watt coaxial attenuators from Midwest Micro wave, http://www.midwestmicrowave.com/. (The “XX” in the part number is repla ced with the numeric attenuation value in dB). __________________________________________________________________ 21 OPTIONAL FEATURES RACK MOUNTING, "-R5" OPTION A rack mounting kit is available. The "-R5" rack mount kit may be insta lled after first removing the one Phillips screw on the side panel adjacent to the front handle. DC OFFSET, "-OT" OPTION This option adds an internally-generated 0 to ±5V DC offset to the main output. The offset level is set by the front-panel controls, or by computer command s. The rear-panel OS switch must be set to “ON” to activate the internally-generated offs et feature. DC OFFSET, "-EO" OPTION This option allows adds a DC offset to the main output, which is contro lled by an externally generated 0 to +10V analog control voltage applied to a rear -panel connector. MONITOR OUTPUT, "-M" OPTION The monitor output provides an attenuated replica (20 dB down) of the v oltage on the main output. The monitor output is designed to operate into a 50 Ohm lo ad. ELECTRONIC AMPLITUDE CONTROL, "-EA" OPTION The output amplitude can be set to track the voltage on this input. Zer o Volts in corresponds to zero amplitude output, and +10V in corresponds to maximu m amplitude out. This mode is activated by selecting "Ext Control" on the front-pan el amplitude menu, or with the "source:voltage external" command. __________________________________________________________________ 22 PROTECTING YOUR INSTRUMENT TURN OFF INSTRUMENT WHEN NOT IN USE The lifetime of the switching elements in the pulse generator module is proportional to the running time of the instrument. For this reason the prime power to the instrument should be turned off when the instrument is not in use. In the case of failure, the switching elements are easily replaced following the procedure describe d in a following section. DO NOT EXCEED 10 MHz The output stage may be damaged if triggered by an external signal at a pulse repetition frequency greater than 10 MHz. USE A 50 OHM LOAD The output stage may be damaged if the output is not terminated into a 50Ω load. __________________________________________________________________ 23 OPERATIONAL CHECK This section describes a sequence to confirm the basic operation of the instrument. It should be performed after receiving the instrument. It is a useful lear ning exercise as well. Before proceeding with this procedure, finish reading this instruction manual thoroughly. Then read the “Local Control” section of the “Programming M anual for -B Instruments” thoroughly. The “Local Control” section describes the fron t panel controls used in this operational check - in particular, the MOVE, CHANGE, and A DJUST controls. AVTECH SAMPLING PULSER OSCILLOSCOPE BW > 10 GHz MAIN OUTPUT 50 OHM INPUT CONNECTOR 40 dB AC ATTENUATOR POWER TRIG TRIG CONNECTOR CONNECTOR ALL CABLES: 50 OHM COAXIAL 1. Connect the pulse generator to a sampling oscilloscope as shown abo ve. Note that: a) The use of 40 dB attenuator at the sampling scope vertical input ch annel will insure a peak input signal to the sampling scope of less than 1 Volt. F actory tests are conducted using Midwest Microwave model ATT-0527-XX-SMA-07 attenuators. b) The TRIG output channel provides TTL level signals (approximately 0 and +3V). To avoid overdriving the TRIG input channel of some scopes, a 20 dB attenuator may be required at the input to the scope trigger channel. c) The bandwidth capability of components and instruments used to disp lay the pulse generator output signal (attenuators, cables, connectors, etc.) s hould exceed 10 GHz. d) Set the oscilloscope to trigger externally with the vertical settin g at 50 mV/div and the horizontal setting at 10 ns/div. __________________________________________________________________ 24 2. Turn on the AVMR-1A-B. The main menu will appear on the LCD. 3. To set the AVMR-1A-B to trigger from the internal clock at a PRF of 10 kHz: a) The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is. b) Press the CHANGE button. The frequency submenu will appear. Rotate the ADJUST knob until the frequency is set at 10 kHz. c) The arrow pointer should be pointing at the “Internal” choice. If i t is not, press MOVE until it is. d) Press CHANGE to return to the main menu. 4. To set the delay to 100 ns: a) Press the MOVE button until the arrow pointer is pointing at the de lay menu item. b) Press the CHANGE button. The delay submenu will appear. Rotate the ADJUST knob until the delay is set at 100 ns. c) The arrow pointer should be pointing at the “Normal” choice. If it is not, press MOVE until it is. d) Press CHANGE to return to the main menu. 5. To set the pulse width to 60 ns: a) Press the MOVE button until the arrow pointer is pointing at the pu lse width menu item. b) Press the CHANGE button. The pulse width submenu will appear. Rotat e the ADJUST knob until the pulse width is set at 60 ns. c) The arrow pointer should be pointing at the “Normal” choice. If it is not, press MOVE until it is. d) Press CHANGE to return to the main menu. 6. At this point, nothing should appear on the oscilloscope. 7. To enable the output: a) Press the MOVE button until the arrow pointer is pointing at the ou tput menu item. __________________________________________________________________ 25 b) Press the CHANGE button. The output submenu will appear. c) Press MOVE until the arrow pointer is pointing at the “ON” choice. d) Press CHANGE to return to the main menu. 8. To change the output amplitude: a) Press the MOVE button until the arrow pointer is pointing at the am plitude menu item. b) Press the CHANGE button. The amplitude submenu will appear. Rotate the ADJUST knob until the amplitude is set at +10V (or -10V for "-N" models ). c) Observe the oscilloscope. You should see 60 ns wide, 10V pulses. If you do not, you may need to adjust the delay setting to a value more compatibl e with your sampling oscilloscope. Repeat step 4 if required. You may also nee d to adjust the sampling scope controls. d) Rotate the ADJUST knob. The amplitude as seen on the oscilloscope s hould vary. Return it to 10V. e) ("-PN" units only) Press the +/- button on the front panel. The amp litude as seen on the oscilloscope should flip polarity, to -10V. f) Press CHANGE to return to the main menu. This completes the operational check. __________________________________________________________________ 26 PROGRAMMING YOUR PULSE GENERATOR KEY PROGRAMMING COMMANDS The “Programming Manual for -B Instruments” describes in detail how to connect the pulse generator to your computer, and the programming commands themselv es. A large number of commands are available; however, normally you will only need a few of these. Here is a basic sample sequence of commands that might be sent t o the instrument after power-up: *rst (resets the instrument) trigger:source internal (selects internal triggering) frequency 1000 Hz (sets the frequency to 1000 Hz) pulse:width 50 ns (sets the pulse width to 50 ns) pulse:delay 20 ns (sets the delay to 20 ns) volt:ampl 5 (sets the amplitude to +5 V) ("-N" units should use "volt:ampl -5) output on (turns on the output) For triggering a single event, this sequence would be more appropriate: *rst (resets the instrument) trigger:source hold (turns off all triggering) pulse:width 50 ns (sets the pulse width to 50 ns) output on (turns on the output) volt:ampl 5 (sets the amplitude to +5 V) ("-N" units should use "volt:ampl -5) trigger:source immediate (generates a single non-repetitive trigger event) trigger:source hold (turns off all triggering) output off (turns off the output) To set the instrument to trigger from an external TTL signal applied to the rear-panel TRIg connector, use: *rst (resets the instrument) trigger:source external (selects internal triggering) pulse:width 50 ns (sets the pulse width to 50 ns) pulse:delay 1 us (sets the delay to 1 us) volt:ampl 5 (sets the amplitude to +5 V) ("-N" units should use "volt:ampl -5) output on (turns on the output) These commands will satisfy 90% of your programming needs. __________________________________________________________________ 27 ALL PROGRAMMING COMMANDS For more advanced programmers, a complete list of the available command s is given below. These commands are described in detail in the “Programming Manua l for -B Instruments”. (Note: this manual also includes some commands that are n ot implemented in this instrument. They can be ignored.) Keyword Parameter Notes LOCAL OUTPut: :[STATe] :PROTection :TRIPped?

With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord and allow the instrument to sit unpow ered for 10 minutes before opening the instrument. This will allow any internal sto red charge to discharge. There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech (info@avtechpulse.com) to arrange for the instrum ent to be returned to the factory for repair. Service is to be performed solely b y qualified service personnel. Caution: High voltages are present inside the instrument during normal operation. Do not operate the instrument with the cover removed. RACK MOUNTING A rack mounting kit is available. The -R5 rack mount kit may be install ed after first removing the one Phillips screw on the side panel adjacent to the front handle. ELECTROMAGNETIC INTERFERENCE To prevent electromagnetic interference with other equipment, all used outputs should be connected to shielded loads using shielded coaxial cables. Unused ou tputs should be terminated with shielded coaxial terminators or with shielded coaxia l dust caps, to prevent unintentional electromagnetic radiation. All cords and cables s hould be less than 3m in length. __________________________________________________________________ 30 MAINTENANCE REGULAR MAINTENANCE This instrument does not require any regular maintenance. On occasion, one or more of the four rear-panel fuses may require repla cement. All fuses can be accessed from the rear panel. See the “FUSES” section for details. CLEANING If desired, the interior of the instrument may be cleaned using compres sed air to dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for instructions on accessing the interior.) No other cleaning is recommend ed. __________________________________________________________________ WIRING DIAGRAMS WIRING OF AC POWER 1 2 3 4 5 6 D o n o t a tte m p t a n y r e p a i r s o n th i s i n s t r u m e n t M a in s c ir c u i t s - h a z a r d o u s liv e . b e y o n d t h e fu s e r e p l a c e m e n t p r o c e d u r e s d e s c r i b e d i n th e m a n u a l .
